Samsung Galaxy S8+ Wifi Calling

Anonymous — Thu, 19 Oct 2017 11:58:32 GMT

Now that o2 is going to be ending it's TuGo service I need to activate wifi calling on my device.

I have requested the 4G and wifi calling through o2 which should be activated in 24 hours however there is no option for me to activate Wifi calling on my S8+.

I have checked the firmware and it is the latest, however not an o2 firmware even though I purchased directly from an o2 store.

I need wifi calling as I get no signal at work, but it looks like I wont be able to make or recieve calls/texts if TuGo is going to end.

Can anyone provide any help on this?

You need O2 firmware for it to work.
We are no longer allowed to tell you how to flash this to your device so you need to go back to O2 and demand they do it for you free of charge.

I think that the settings only become active once it has been turned on for your contract.
The other place to check (as per these - https://www.o2.co.uk/help/network-coverage-and-international/wifi-and-4g-calling - instructions) is the CSC.
Dial *#1234# and check it includes "TEF".

I followed this and confirmed that it did not include TEF so I do not have the o2 firmware on my device which I purchased directly from o2.
If it isn't available in a day or two I may have to consider switching to another provider after quite a few years with o2.

The o2 firmware won’t magically appear on your phone.
O2 will have to have it to flash the correct firmware for you.

^^ That.
Take the phone (with receipt) back to the shop you got it from.
Tell them that they need to provide a device with the correct firmware on it so you can use the service they are providing.

When you say bought from O2 was it a physical O2 store and not via a 3rd party for example Carphone Warehouse, mobiles.co.uk, etc

It does say "even though I purchased directly from an o2 store."
We do know that some of o2's phones don't have o2 firmware on and some are unlocked, but surely if you are going to restrict services to "phones bought from o2" you should at least make sure they are capable of receiving said services?

I'm pretty sure that it was a physical o2 due to the fact that there was a huge o2 sign and everything was branded o2, even down to the employees. So yeah pretty confident in that haha.

Now that I am home I checked the settings again to enable WiFi calling and it has now appeared as as the second option on screen (Settings >Connections >WiFi calling). Will check again to see if the wifi at work isn't causing an issue or it is possible that this has been activated after I requested it from O2.

You must be on o2 firmware then if it's working now?

I guess o2 should update their own instructions because according to their own instructions it is not supported:

From https://www.o2.co.uk/help/network-coverage-and-international/wifi-and-4g-calling#how-do-i-set-up-wifi-and-4g-calling-iphone7

"To check if your phone's running O2 firmware, dial *#1234# and look at the CSC entry. If this doesn't include TEF in the text then Wifi and 4G Calling isn't supported on your phone right now. If you need more info, get in touch"

I guess once you request for o2 WiFi calling to be enabled the option will appear.

Thanks for the help guys. Much appreciated.

No it’s not I’m afraid.

Have you tried to force an update?

Re: Samsung Galaxy S8+ Wifi Calling

JFA — Fri, 27 Oct 2017 16:58:54 GMT

Yes no updates available.
Got phone on o2 contract but from carphone wearhouse.
Any chance Wi-Fi calling will be available on o2 with non o2 firmware?

Allegedly if you believe what customer service are saying but I wouldn’t hold your breath!

Go to Settings then Apps then select "Show system apps" from pull down menu. then scroll down to the Phone app (the first of 3 with the largest storage figure (780 Kb in my case), then select More settings, then scroll down the screen where you will finally find the W-Fi calling option.
